HAM BOILER.

Application led. May 5, 1924.

This invention relates to appliances for the cooking of hams or othermeats in the piece or other food products in any bulk form, withprovision for molding or compressing' the same during the cookingaction.

Among the objects of the invention is to provide a cooking' receptacle,referred to hereinafter for convenience as a ham boiler, having areceptacle or body portion, a cover or closure for the receptacle,improved hand power fastening means between the closure and thereceptacle, and with a resilient cushion means associated preferablywith the cover to compensate for variations in bulk during the cookingaction, such as would result from either swelling or contraction of thecommodity or the like, and to provide peculiar and novel means forattaching the fastening and handle means to the cover and provideimproved seats for the cushion devices.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying` drawings, in which like reference characters designate thesame parts in the several views, and in which- Figure 1 is a verticalsectional View approximately along the vertical central plane of thedevice.

Fig. 2 is a plan view.

Fig. 3 is an end elevation.

Fig. 4E is a detail of a modification.

Fig. 5 is a plan view of the same.

Referring now more specifically to the drawings I show a receptacleformed as by stamping or the equivalent from sheet metal of any suitablestrong, rigid, non-con rodible material. This receptacle is shown,especially in Fig. 2, as of oval form but with substantially verticalwalls and is provided around its upper open top with an outwar lyprojecting flange 11, said flange lying substantially in a horizontalplane except at the ends where downwardly deflected lips 12 areprovided. f

The cover or closure 13 is substantially a flat member but having adownwardly turned marginal flange 111 which is adapted to move downwardfairly close to the in- Serial No. 711,1e6. p

ner surfaces of the receptacle walls. The main portion of the cover is`substantially flat and imperforate, a form best calculated for ready,easy, and relatively cheap construction from sheet metal as by stamping.

15 indicates a handle or bar of any suitable material or constructionas, for instance, a casting having forks 16 at its ends and havingformed along the lower surface not far from the respective ends a pairof bosses 17 forming seats, and these bosses are pr0- vided with centralvertical holes 18 which merge into counter bores 19 at the top of thebar. 20 indicates a pair of catch members in the nature of racks whichmay be formed in any convenient manner and each havingat its upper end aknuckle portion 21. Each catch 20 is suspended by a pivot pin 22 passedthrough the spaced lugs of a yoke shaped hand power lever 31, said lugs30 in turn being pivoted on pins 32, eccentric to the pin 22 andattached to the ends of the fork 16. In the open position of the partsthe levers 31 are directed upward as in dotted lines of Fig'. 1 and withthe rack pivots 22 below the pivots 32. W'hen the levers 31 are thenswung outward from each other and downward the pivots 22 are swungaround or past the vertical plane of the pivots 32, relatively, insuringthat the levers 31 will be self retained against the racks and with thesprings under suiiicient compression for the purpose of the device. Theracks are afforded a sufficient degree of tilting around the respectivelips 12 to enable the aforesaid relative movement or interchange ofposition of the two sets of pivot pins.

In the modified form of Figs. 4 and 45 the levers 31a swing upward'andtoward each other into locking and holding position. Otherwise theaction is substantially` the same in both arms. The ends of the bar,however, are in the form of simple knuckles 16a instead of forks asabove described, and the upper end portion of each rack 2O consists of apair of spaced lugs 21a instead of a simple knuckle 21.

A pair of springs 24 are shown interposed between the bar 15 and thecover 13 to afford the desired resiliency or cushioning eect abovereferred to. The upper ends of the springs are seated upon or around thebosses 17 while the lower ends of the sprinefs are seated upon or arounda pair of housings 25.

Each housing 25 consists of a hollow boss 25a for the reception andaccommodation of a nut 26 within it, and integral with the boss 25EL isa horizontal flange 25h. rIhese hous ings are readily formed from sheetmet-al by stamping or the like and the material there` of is of such anature as to be readily and directly connectible to the upper surface ofthe cover 13. As shown at 27 the preferred manner of securing thehousings 25 to the cover is by direct welding et the flanges to thecover. This may be by any suitable process such as spot welding,acetylene welding or its equivalent, but in any event the connection isstrong, rigid, and permanent, and the nut 26 is then retained withineach dome or boss 25a. rEhe boss 25 is preferably formed as a counterpartot the form in plan oi'f the nut, shown as hexagonal, so as to holdthe nut from rotation. Within the center oi the top of the boss formed asmooth hole 25. The attachment means between the bar 15 and the coverconnections are shown as consisting ot a pair ot bolts 28 whose lowerthreaded ends project freely through the holes 25c and have threadedengagement within the nuts 26 while the extreme ends thereo't bitesnugly against the original surface ot the cover below the nuts, therebylocking the bolts rigidly in place as anchored by the bolt nuts. Theupper shoulder portions ot the bolts have slidable movement in the holes18 ot the bosses 17 while the heads normally are depressed within thecounter sinks 19u When,y however, the bar is depressed 'torceably withrelation to the cover, compressing the springs 24, the head ends ot thebolts may project upward somewhat above the normal position. Thus Iprovide by means et the housings 25 and the parts co-operating therewitha substantially permanent connection between the bar and the cover andwith interposed cushions, such connections, how-- ever, being removableor interchangeable in the event ot necessity at any time by the use oftools, although the housings are retained as rigid fixed parts of thecover.

In operation a ham or its equivalent after being made or prepared is putdirectly into the receptacle, and the cover being manipulated by thehandle, or bar 15, is put directly upon the ham, the operator bringingdownward upon the ends of the bar only about enough :torce to insuretemporary holding ot the catch members upon the lips l2. ylhen thelevers 31 are swung around their pivots 22 and 32, according to theconstruction or manner of hanging the racks above described, bringingthe pivots 22 past the dead centers ot the pivots 32 and insuring theproper degree of compression of the ham within the receptacle. It willthus be seen that a very moderate amount ot torce applied to the levers31 will insure ample compression of the springs and ham and suchcompression will react in such a manner with respect to the two sets otpivotpins as to insure selt locking of the parts. The levers, however,are easily swung to unlocking position when thc cover is to be removed.

I claim:

1. In a ham boiler, the combination 'of a metal cover, a handle spacedabove the cover, and connections between the cover and the handlecomprising a bolt extending Jfrom the handle to the cover and having itscover end threaded` a metal housing welded to the cover and having ahollow boss with a hole therethrough through which the threaded end otthe bolt projects, and a nut housed within the boss and having threadedinterlocking engagement with the end of the bolt, the threaded end otthe bolt having biting engagement directly with the surface ci the coverwithin the housing.

2. In a ham boiler, the combination with a receptacle and a covermovable within said receptacle to compress the contents thereof, otcombined power application and locking means for said cover comprising ahandle and a lever having pivotal engagement with the handle, and a hookhaving` direct eccentric pivotal engagement with said lever andextending' downwardly into engagement with the receptacle, whereby whensaid lever is swung about its pivot to lie alongl the top ot the handleand in locking position, a downward torce is exerted upon said cover todepress the same into the receptacle and to lock it in position.

In testimony whereof I affix my signature.

HANS ADELMANN.
